Patented Nov. 24, 1931 SAMUEL? SOMMER, OF SAN' FRANCISCO, CALIFORNIA HAIR CLAMPING DEVICE Application filed May 15,

'lhis invention relates to appliances utilized by hairdressers when waving hair.

When waving hair by what is known as the permanent wave system a protecting l clamp is clamped on a portion of the hair adjacent the scalp and the hair is wound on a mandrel and clamped adjacent the protecting device. A heater is then arranged over the wound hair to dry and curl it. .It is the principal objectk of the present invention to generally improve the construction and operation of protecting and claInp-,4

ing devices of the character referred to.

One form which the invention may assume,

is exemplified in the following description and illustrated by way of example in the ac companying drawings, in which Fig. 1 is a perspective view of the clamping devices embodying the present invention shown in clamping position.

Fig. 2 is a plan view of the same.

Fig. 3 is a transverse section showing the clamping devices assembled on the hair.

Fig. 4 is a perspective'view of the protecting clamp in open position. l

Fig. 5 is a fragmentary view in perspec-v tive showing the mannerin which the outer clamp embraces the end of the protecting clamp. y i

Fig. 6 is a perspective view of the removable end portion of the protecting clamp.

Fig. 7 is a perspective view of the'outer clamp in open position.

Fig. 8 is a perspective view of the mandrel used in connection with the clamps.

Referring more particularlyvto the accompanying drawings, 10 indicates a protecting clamp and 11 the outer clamp. The protecting clamp 10 comprisesa pair of rigid clamping arms 12 and 14 which are covered by a removable slip 15 of rubber or similar yieldable material. At one end of the clamp the adjacent ends of the arms 12 and 14 are con- 45 nected by means of a link 16. This link permits the arms 12 and 14 to be relatively folded into a position where they will lie in parallelism as illustrated in Figs. 1, 2 and 3. EX-

tending at right angles to the link 16 and J( formed integrally therewith is a bearing lug 1929. Serial No. 363,251.

17 the purpose of which will be hereinafter described.

At its free end the arm 12 is formed with a slotted opening 18. A pair of links 19 are provided for this end of the arm. These links are spaced apart and at one end they are connected together by a pin 20. Pivotally disposed between the opposite end of the links 19 a latching lever 21 which is formed with a cam end 22 slightly eccentric to the 60 i pivot pin 23 by means of which it is connected to the links 19.

To connect the links 19 to the arm 12 the slotted end of the arm 12 is inserted be-v tween the links and the slotted opening 18 is 65 engaged with the pin 20, forming an articu-` late connection between the arm 12 and the links 19.

The purpose of having the latching assembly connected to the arm 12 in a manner 70 whereby it may be easily disconnected therefrom', is for the purpose of permitting the coverings 15 on the arms 12 and 14 to be readily replaced. If the latching assembly Y i was permanently connected to the arm-12 it 'i5 would be practically impossible to change the rubber covering on the arm 12.

One of the links 19 is formed with a bearing lu 24 similar to theA bearing lug 17 on v the lin 16. When the arms 12 and 14 lie 80 in parallelism the bearing lugs 24 and 17 are arranged in alignment as shown in Figs. 1 and 2 so as to receive the ends of a mandrel 25a.

The free end of the arm 14 is adapted to be 85 projected between the links 19 when the clamp is to be held in clamping or folded position; When in'this position the latch lever 21 may be turned so that its cam end 22 will bear against the outer end of the 90 arm 14 and tend to clamp it tightly against the opposite arm 12.

The outer clamp 11 is constructed substantially the same as the device 10, being fitted with arms 25, a clamping assembly 26 and 95 a link 27 connecting adjacent ends of the arms 25. The clamp 11 is operated in the same way as the protecting clamp 10. I wish to point out, however, that the inner edge of each arm .25 is formed with apair of re-.190

cesses 28 one of which is locatedcontiguous to each end of the arm. The recesses of each arm are adapted to align when the arms 25 are folded to clamping position. When the outer clamp is assembled on the protecting clamp, the aligned recesses 28 align With the bearing lugs 17 and 24 so as to latch the outer clamp with respect to the inner clamp and to permit the arms 25 of the outer clamp to be drawn tightly together.

ln operation of the devices, the protecting clamp 10 is clamped over a strand of hair With its rubber covered surfaces lying close to the scalp. The strand of hair is then Wound on the mandrel 25a and the ends of the mandrel are engaged with the bearing lugs 17' and 24. The hair around the mandrel is then covered with flannel and paper and the clamp 11 is positioned as shown in Figs. 1 to 3 inclusive. The clamp 11 tightly clamps the covering over the Wound hair and forms in eiiect a steam-tight lioint between the mandrel and the scalp. Further than this. as the outer clamp interlocks with the protecting clamp,l the Wound hair Will be held in perfect position with respect to the inner clamp. The heater is then applied to the Wound hair and when the hair has become perfectly dry the heater and the clamps are removed and the hair unwound from the mandrel.

Should the covering 15 on the arms 12 and 14 of the protecting clamp 10 become soiled, the latching assembly may be disconnected from the end of the arm 12 and the rubber coverings 15 on the arms 12 and 14 removed and replaced.

While l have shown the preferred form of my invention, it is to be understood that various changes may be made in its construe tion by those skilled in the art Without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. device of the character described comprising a protecting`clamp. a mandrel upon which hair may be Wound and positioned relative to and supported by the protecting clamp. an outer clamp adapted to be interposed between the protecting clamp and the mandrel. means forming an interlocking connection between the protecting clamp and the outer clamp` said outer clamp being adapted to maintain a textile covering over the hair that is Wound upon the mandrel.

2. A device of the character described in,

cluding a protecting clamp comprising a pair of arms, a link connecting the arms together at one end, a pair of links pivotally connect ed at one end to the free end of. one of said arms, said pivotal connection being adapted to be disengaged whereby the links may be disconnected from said arm, said links being Leases@ adapted to be positioned when the arms are in parallelism to embrace the end of the opposite arm, a latching lever pivotally connected to the free end of said links between the links, said latching lever having a cam end engageable With the end of the arm inserted between the links to press the arms together, a bearing lug projecting at right angles to the link connecting the ends of the arms, a similar bearing lug extending at right angles from one of the pair of links,'said bearing lugs projecting in the same direction and adapted to be disposed in alignment when the arms lie in parallelism, an outer clamp including a pair of arms, a link connecting one end of said arms, said arms being formed with aligned recesses adapted to be engaged with the bearing lugs on the protecting clamp, and a clamping mechanism associated with the free ends of the arms of the outer clamp to connect said arms and press them tightly toward each other.

3. A device of the character described comprising a mandrel upon which hair may be wound, a protecting clamp and an outer clamp, said protecting clamp having a pair of extensions formed on its ends engageable with and adapted to support both the mandrel and the outer clamp.

4. A device of the character described comprising a mandrel upon which hair may be wound, a protecting clamp and an outer clamp, said protecting clamp having a pair of extensions formed on its ends, said outer clamp having notches formed therein and adapted to embrace said extensions when the outer clamp is in a closed position, and means carried by the extensions to receive and support the mandrel.
